- Add `columns` parameter to `get_ohlc_async` and pass through to Iceberg queries - Replace hardcoded Binance field extraction with declarative `EXCHANGE_OHLCV_EXTENSIONS` config - Add `applyScale` helper for field-specific transformations (ms_to_ns, price, size, int) - Support `complementOf` spec for derived fields (e.g., sell_vol from total - buy_vol) - Apply extensions dynamically in `convertToOHLC` and gap-filling logic - Remove redundant column filtering in DataAPI (now handled upstream)
